Dwell as economic indicator

While walking back from the mailbox today, I was reminded of the old "number of pages in WIRED closely matches the NASDAQ" thing as I heaved the latest Dwell magazine back to my house. I have about three or four years of back issues in my new bookshelf and just looking at the spines, it appears that the magazine has gone from ~75 pages to about 300 in each issue. That kind of bloat can't go on forever and I know they're becoming a popular brand but I have a feeling there's a direct relationship between how well people are doing financially and how much they care about how modern their house looks.
